摘要
为明确玉米不同品种(系)之间的抗螟性差异,采用田间自然感螟法,于2010-2011年在甘肃省天水市甘谷县对478份玉米种质资源进行田间抗性鉴定。结果表明:在216份农家种资源、216份自交系和46份杂交种中共筛选出高抗材料86份、抗螟材料85份、中抗材料167份,分别占供鉴材料的18.0%、17.8%和34.9%;其余140份为感螟和高感材料,占29.3%。
So as to confirm the borer-resistance differences among different corn varieties ( inbred lines ) , the study adopted the method of being naturally infected by Ostrinia furnacalis under field conditions , and identified the resistance of 478 maize germ-plasms to corn borer in Gan ’ gu county, Tianshui city, Gansu province from 2010 to 2012.The results showed that: among 478 maize germplasms (216 peasant variety resources , 216 inbred lines and 46 hybrids), 86 high-resistant materials (18.0% of all materials), 85 borer-resistant materials (17.8%), 167 middle-resistant materials (34.9%) were screened out;the other 140 materials were susceptible or highly susceptible to corn borer , accounting for 29.3%of all tested materials.
